Preface

Precautions

Follow the procedures listed below to ensure safe handling of components and to

prevent harm to yourself and the NetServer.

WARNING The HP NetServer LH 3r weighs up to 160 pounds (73 kg.)

when fully loaded. If you are removing the LH 3r from the

rack, remove the power supplies and hard disk drives before

doing so. Follow all local regulations when lifting the

NetServer.

To prevent the rack enclosure from tipping over,

•

Extend the anti-tip foot on the rack

•

Verify that the leveling feet on the rack are lowered

•

Do not extend more than one piece of equipment at once

Before removing the cover, always disconnect the power cord

and unplug telephone cables. Disconnect the power cord to

avoid exposure to high energy levels that may cause burns

when parts are short-circuited by metal objects, such as tools

or jewelry. Disconnect telephone cables to avoid exposure to

shock hazard from telephone ringing devices.

Note that the power switch does not turn off the standby

power. Disconnect the power cord to turn off standby power.

If the backlight on the LCD display is on, standby power is

still on.

CAUTION Never operate this NetServer without first installing all covers

and the front bezel. Operating the system without all covers in

place reduces critical cooling airflow over some components,

such as hard disk drives and processor modules. Operating the

system without all covers in place may result in failure of these

components.

Wear a wrist strap and use a static-dissipating work surface

connected to the chassis at all times to prevent possible static

electricity damage to the NetServer components.

1 Introduction

Installation Overview

This guide describes the procedures for installing new hardware and software in

your LH 4/LH 4r NetServer. The hardware update takes 10 or 15 minutes. The

firmware update can take up to an hour, not including time taken by backing up

and restoring your hard disk drives, or by reinstalling the NOS or applications.

During the update procedure, you will see progress screens that indicate the action

underway.

During the software upgrade, you will:

• update system information

• reconfigure options like interrupt management and NetRAID details

• reinstall the NOS if necessary

NOTE Before attempting the upgrade procedure, you should be

familiar with the current and default NetRAID configurations

and with the BIOS options specified in the Setup utility. For

further information, refer to these topics on the HP NetServer

Online Documentation CD-ROM:

HP NetRAID Installation and Configuration Guide

HP NetRAID User Guide

Setup Utility (in LH 4/LH 4r Configuration section)

CAUTION The software update eliminates user-definable BIOS options

and the NetRAID configuration details. You must save these

details before you perform the software upgrade if you want to

restore these settings afterward.

Chapter 1 Introduction

CAUTION After the system information update, your NetServer will

revert to the default NetRAID settings. You must restore your

NetRAID configuration from your worksheets or from notes

before you can access the NetRAID arrays. If you do not save

the NetRAID configuration details before performing the

system information update, your data may be unrecoverable.

Briefly, the conversion takes several steps:

1. Back up the contents of your hard disks - both the system disk(s) and any

RAID arrays.

2. Save the current system software configuration with the LH 3/LH 3r

HP NetServer Navigator CD-ROM.

3. Gather the documentation, tools, hardware, and software needed to perform

the conversion.

4. Perform the first part of the software upgrade, backing up data.

5. If you are upgrading an LH 3r, extend it from the rack. Be sure to extend

the anti-tip foot, or use the anti-tip feature, before you extend the NetServer

from the rack.

6. Remove cover 2, the cover protecting the top of the CPU baseboard, and

cover 3, the cover shielding the components on the CPU baseboard side of

the LH 3.

7. Remove the LH 3 CPU baseboard.

8. Install the power supply upgrade kit, or additional power supplies, if

necessary.

9. Remove the CPU card guide and air baffle used with the old CPU

baseboard.

10. Install memory and processors in the LH 4 CPU baseboard.

11. Install the chassis reinforcement bars.

12. Install the LH 4 CPU baseboard in the chassis.

13. Replace the covers.

14. Perform the second part of the software update from the HP NetServer

Navigator CD-ROM and LH4UPD diskette.

Chapter 1 Introduction

15. Reconfigure the system with the Setup and NetRAID utilities, using the

configuration details you saved in step 2.

16. Verify that the system is restored to its operating configuration.

NOTE This procedure assumes that you are not performing other

procedures, such as installing new PCI cards, tape drives, or

other hardware, or performing operating system upgrades, at

this time. You can do these operations while performing the LH

3 to LH 4 upgrade, but minimizing changes makes

troubleshooting much easier if problems or incompatibilities

arise during the upgrade process.

Chapter 1 Introduction

Saving the Current Operating Environment

Before you start the upgrade, follow these instructions to preserve the current

operating environment.

CAUTION You must back up all disks on your system - the disk

containing the NOS and any RAID arrays. Failure to perform

this step leaves you vulnerable to potential loss of data.

1. Back up all hard disks - both the hard disk containing the NOS, and any

RAID arrays, using the backup utilities on your NOS. You will perform a

restore later to replace this data.

2. You must write down all system configuration details from the Setup,

Remote Management, and NetRAID utilities, as you will have to

reconfigure them after the system software update. For a discussion of

NetRAID implementation and usage details, refer to the HP NetRAID

Installation and Configuration Guide and HP NetRAID User Guide

manuals on the HP NetServer Online Documentation CD-ROM.

For example, note the following information:

A. Adapter:

∗ PowerFail Safeguard (Default is Enabled)

∗ Cache Flush Timings (Default: every 4 seconds)

∗ Rebuild Rate (Default: 50%)

∗ Auto Rebuild (Default: Enabled)

B. Logical Drive:

∗ RAID level

∗ Size

∗ Stripe Size (Default: 64 KB)

∗ Write Policy (Default: Write Through)

∗ Read Policy (Default: Adaptive)

Chapter 1 Introduction

∗ Cache Policy (Default: Cached I/O)

∗ Virtual Sizing (Default: Disabled)

C. SCSI Channel:

∗ Transfer Rate (Default: Ultra-2)

3. If you are using the Integrated Remote Assistant features, run the Integrated

Remote Assistant. Record all configuration settings.

4. Ensure that the following features in the Integrated Remote Management

utility are not enabled:

◊ Power off on critical temp

◊ Power off on critical voltage

5. From the "More NetServer Utilities" option in the Main Menu, view the

Event Log Report Utility. If there are problems with the system,

troubleshoot these before continuing with the upgrade. Refer to the HP

NetServer LH 3/LH 3r User Guide and the HP NetServer Online

Documentation CD-ROM.

Preparing for Hardware Upgrade

Gather the tools and the setup information you need before beginning the

conversion. Locate the HP NetServer where there will be sufficient space to

remove the covers. Reserve bench space at a comforTable level so you can add

processors, VRMs, and memory easily.

Follow these steps:

1. Shut down the network operating system.

2. Turn off the NetServer and display.

3. Disconnect all telephone cables and power cords.

4. Disconnect all cables attached to the system board connectors at the rear of

the chassis.

Chapter 1 Introduction

Upgrading the Rack (LH 3r) Configuration

You can upgrade the LH 3r rack configuration without removing it from the rack,

but you may find it easier to reinstall the CPU baseboard and install the chassis

reinforcement bars when the LH 3r is removed from the rack and sitting on a

workbench. When in the rack, the chassis reinforcement bars mount on the bottom

of the LH 3r. If you do decide to remove it from the rack to perform the upgrade,

refer to the documentation below.

CAUTION Do not pull the LH 3r forward in the rack without extending

the anti-tip foot. If the anti-tip foot is not extended, the rack

assembly can tip over and injure you and damage the

NetServer or rack.

For HP Racks

Refer to the HP NetServer LH 3/LH 3r User Guide. For cabling instructions, refer

to the documentation that came with the rack, and to the Rack Cabling Reference

for the HP NetServer LH 4.

For Non-HP (Compaq) Racks

Refer to the HP NetServer LH 3r Installation Guide for Compaq

4000/7000

Racks. For cabling instructions, refer to the documentation that came with the

rack, and to the Rack Cabling Reference for the HP NetServer LH 4.

2 Removing Covers and the CPU

Baseboard

CAUTION Wear a wrist strap and use a static-dissipating work surface

connected to the chassis at all times.

Before you can install the new LH 4 CPU baseboard, there are several components

to remove from the LH 3:

• Remove the bezel and covers 2 and 3 to get access to the HP NetServer’s

interior

• Remove the LH 3 CPU baseboard

• Remove the old CPU baseboard guide and the air baffle from the LH 3

chassis.

Removing the Bezel and Covers

The HP NetServer has three hand-removable cover panels and a bezel:

3 Installing LH 4 Components

WARNING Do not use memory or VRMs from the LH 3/LH 3r CPU

baseboard with the LH 4/LH 4r CPU baseboard. This may

result in damage to components and put data integrity at risk.

Upgrading the HP NetServer LH 3/LH 3r to an HP NetServer LH 4/LH 4r requires

several steps, but there are few differences between the two NetServers.

Remove any packing materials and position the following components where you

can reach them from your work position.

CPU Baseboard Components

The LH 3/LH 3r has a CPU baseboard that accepts two Intel Pentium II

™

Xeon



processors, each with an associated Pentium II Voltage Regulator Module (VRM).

The LH 4/LH 4r has a new CPU baseboard that accepts up to four Intel Pentium II

Xeon processors and six new VRMs designed especially for the Intel Pentium II

Xeon processors.

Figure 3-1 shows the CPU baseboard as it looks after unpacking.

Figure 3-2. CPU Baseboard Layout

Processor and VRM Configurations

The HP NetServer’s CPU baseboard has four processor slots, labeled Processor 1

through Processor 4. It also has six voltage regulator module slots, labeled VRM

1/2, VRM 3/4, VRM 1, VRM 2, VRM 3, and VRM 4. VRM 1/2 and VRM 3/4

provide regulated power for the cache memory on the processors, and the other

four VRMs supply power to the processors themselves. Figure 3-1 shows these

slots on the CPU baseboard.

Add processors in ascending slot order. You must also add additional voltage

regulator modules (VRMs) as you add processors, again in ascending slot order.

There will always be VRMs in slots VRM 1/2 , VRM 3/4, VRM 1, and VRM 2, so

a VRM is added to each corresponding slot as you install a new processor.

Refer to Table 3-1 to determine which VRMs must be installed for each processor.
